Lobbying is a crucial practice in shaping legislation as it allows interest groups to influence lawmakers on specific issues. Through lobbying, organizations can present research, expert opinions, and testimonies to persuade legislators to adopt or modify policies that align with their interests. This can include offering political contributions or facilitating relationships with constituents to demonstrate public support. However, lobbying can lead to unequal representation, where affluent groups have more access and sway over lawmakers, potentially resulting in legislation that favors special interests over the common good.
